The numerical-analytic technique for finding electric and magnetic components of electromagnetic field in a piecewise homogeneous conductive half-space is suggested. Electromagnetic field is excited by a horizontal contour with current harmonically changing in time. The problem is formulated and solved by means of the boundary element method.
